However, we noticed customers still struggling to deploy complex use cases when accuracy requirements are high (\u0026gt; 95%). This is because OCR and parsing is only one part of the problem, and real world use cases need to bridge the gap between raw outputs and production-ready data.\n\nExtend uniquely solves this by unifying models, infrastructure, and tooling into a single platform for end to end document processing.\n\nThis includes:\n\n* Process any document format with state-of-the-art parsing powered by VLMs and OCR\n* Capture precise data with multi-step extraction powered by semantic chunking, bounding boxes, and citations\n* Tackle the most complex use cases with processing modes for document parsing, classification, extraction, and splitting\n* Deploy faster with low code tooling that empowers your entire team to quickly iterate, review results, and improve accuracy\n* Continuously improve results with fine-tuning pipelines that turn reviewed corrections —\u0026gt; custom models\n\nFor example, Extend’s built-in evaluation tools to help you benchmark performance, improve accuracy, and deploy with confidence.\n\n![uploaded image](/media/?type=post\u0026id=87403\u0026key=user_uploads/137869/801788f4-a72c-4d1a-8dd0-d4e9f9f18436)\n\nOur customizable document splitter identifies each distinct section and their relationships according to your instructions. This is critical when ingesting lengthy documents (or multi-document packages).\n\n![uploaded image](/media/?type=post\u0026id=87403\u0026key=user_uploads/137869/f0c2726e-b58f-42fc-8a9a-2b5294c5751d)\n\nHere’s an example of zero-shot table extraction on a complex healthcare doc. What enables this is vision models specialized for tabular structures, working alongside our bounding box citations \u0026 human-in-the-loop review system.\n\n![uploaded image](/media/?type=post\u0026id=87403\u0026key=user_uploads/137869/df2d9e80-2ade-4730-98ed-f0a15f942450)\n\n# Hear it from our customers\n\nMatt Hodgson, CTO at Vendr:\n\n\u003e We did a bakeoff, and Extend had the best results of any solution on the market. It eliminates an entire class of engineering problems around accuracy we don’t want to worry about.\n\nAdam Litton, Staff Engineer at Checkr:\n\n\u003e Extend eliminates the maintenance cost of model tuning, scoring, evaluations, and more. We’re able to focus on our core experience instead of managing the infra.\n\nFabio Fleitas, CTO at Tesorio:\n\n\u003e I don’t know what you guys are doing under the hood, but it’s so much more accurate than any other tool we’ve tried.\n\n# Get Started\n\nIf you’re building document processing pipelines with high accuracy requirements, get in touch with us!\n\n* [Book a demo](https://extend.cal.com/extend/extend-intro-call)\n* Email us at [founders@extend.app](mailto:founders@extend.app)","slug":"Mjj-extend-unified-document-processing-platform","created_at":"2025-02-04T15:46:20.176Z","updated_at":"2026-05-25T04:02:30.995Z","total_vote_count":34,"url":"https://www.ycombinator.com/launches/Mjj-extend-unified-document-processing-platform","share_image_url":"https://www.ycombinator.com/media/?type=post\u0026id=87403\u0026key=user_uploads/137869/a0dc2100-5072-45e4-92c3-d6088bf15bdf","company":{"id":27871,"name":"Extend","slug":"extend","url":"https://www.extend.ai/","logo":"https://bookface-images.s3.amazonaws.com/small_logos/184d30d91903380caada7f52cd7cd7992759e07b.png","batch":"Winter 2023","industry":"B2B","tags":["Documents","Developer Tools","B2B","AI"],"search_path":"https://bookface.ycombinator.com/company/27871"}}
